PITCH ADJUSTMENT ASSEMBLY FOR MACHINE-MOUNTED TOOL
An assembly is disclosed for use in adjusting a pitch of a tool relative to a machine. The assembly may have a link with a first end connectable to the tool and a second end connectable to the machine. The assembly may also have a bushing configured to engage a slot in at least one of the machine and the tool. An offset bore may be formed in the bushing. The assembly may also have a pin passing through the offset bore of the bushing and the link. The bushing may be reconfigurable between a plurality of discrete positions within the slot to incrementally adjust the pitch of the tool relative to the machine.
BLADE SUPPORT FRAME FOR DOZER AND METHOD OF MANUFACTURING THE SAME
An embodiment of the present disclosure relates to a blade support frame for a dozer, which supports a blade, the blade support frame including: a ball joint configured to support the blade so that the blade is rotatable; a front plate coupled to the ball joint; an upper plate disposed on an upper portion of the front plate and coupled to the front plate; a lower plate disposed on a lower portion of the front plate and coupled to the front plate; and an inner diaphragm disposed between the upper plate and the lower plate and configured to support a portion between the upper plate and the lower plate.
Birds-eye-view as cailibration for grade control
A system includes calibrating a grade control system of a work vehicle having a controller operatively connected to a camera. A plurality of cylinders operative to move a blade on the vehicle. The blade includes one or more blade markers. One of the cylinders moves to a predetermined configuration that is between 0% and 100% of maximum stroke length, and the camera takes a corresponding image of the one or more blade markers. The controller measures a corresponding location of the one or more blade markers using the corresponding image and calibrates the grade control system based on the corresponding location of the one or more blade markers. The stored corresponding location can be an initial calibration location or a corresponding calibration location that was previously determined during operating conditions of the work vehicle. The grade control system is calibrated in real-time while the work vehicle is operating or stationary.
System and method for controlling bulldozer
A controller determines that a signal from an operating device represents either a normal operation to manually control a blade or a trigger operation to automatically control the blade. The controller moves the blade so that the angle of the blade is changed in accordance with the operation of the operating device when the signal from the operating device is determined as representing a normal operation. The controller moves the blade until the angle of the blade reaches a predetermined target angle when the signal from the operating device is determined as representing the trigger operation while the bulldozer is traveling.
METHOD OF CONTROLLING A GRADING ATTACHMENT ON A SKID STEER VEHICLE
A method of controlling a grading attachment on a skid steer vehicle that includes the steps of lowering a main arm of a skid steer vehicle with either an electric non-hydraulic cylinder or a drive motor to the main arm’s lowest allowed position along an arm translation path on the skid steer vehicle and adjusting, while the main arm is the in the lowest allowed position, either or both a pitch axis movement and/or a yaw axis movement of a grading attachment coupled to the main arm autonomously using an automatic grade control system implementing at least one of a laser, a GPS, an LPS, and an ultrasonic sensor and with at least one a plurality of electric non-hydraulic cylinders and drive motors, wherein the automatic grade control system is communicatively coupled to the at least one a plurality of electric non-hydraulic cylinders and drive motors.
GROUND ENGAGING TOOL CONTROL SYSTEM AND METHOD
A ground engaging tool control system including a first sensor system, a second sensor system, a first actuator system, a second actuator system, and an electronic data processor. The first and second sensor systems detect respective positions of a first ground engaging tool and a second ground engaging tool. The first actuator system is coupled to the first ground engaging tool and the second actuator system is coupled to the second ground engaging tool. The electronic data processor determines a target grade profile and generates two or more control signals to adjust target positions of the first ground engaging tool and the second ground engaging tool. The target position of the second ground engaging tool is determined based on at least one of a position of the first ground engaging tool or the comparison of a current grade profile and a desired grade profile.
AUTOMATICALLY STEERING A MOBILE MACHINE
A method for steering a mobile machine includes automatically steering the mobile machine in a track steering mode, determining a load condition of the mobile machine, and automatically steering the mobile machine in the track steering mode and a blade steering mode, simultaneously, based on the load condition of the mobile machine.
Earth-moving machine sensing and control system
An example work machine control system may include cost factor logic to obtain a cost factor for a resource, cost variable logic to obtain a consumption signal from a consumption sensor indicative of consumption of the resource, fill measurement logic configured to receive a fill signal from a fill sensor, the fill signal indicative of a fill state of a container of an earth-moving work machine, fill target logic to determine a target fill level for the container based on the cost factor, the consumption signal and the fill signal and control logic to generate a machine control signal based on the target fill level.
WORK MACHINE WITH AN ADAPTIVE CONTROL SYSTEM AND METHOD FOR GRADE CONTROL
An adaptive control system automatically controls an attachment position during a grading operation of a surface. The system comprises a frame, an attachment, first sensor, a second sensor, a laser receiver and a controller. The first sensor generates a first sensor signal indicative of an angle of the frame. The second sensor generates a second sensor signal indicative of an angle of the ground-engaging attachment. The laser receiver receives a laser signal from a laser beacon and generates a height signal based on the laser signal. The height signal is indicative of a position of either the attachment or the frame relative to the laser signal. The controller establishes a target grade based on a desired grade of the surface; identifies a position of the attachment; receives the first sensor signal; the second sensor signal; and the laser signal. The controller generates a first control signal or second control signal based on the inputs.
Work machine
A load sensing valve maintains a differential pressure at a set pressure by controlling a regulator in accordance with a differential pressure between a discharge pressure of a hydraulic pump and a load pressure of hydraulic actuators. A set pressure control device controls the set pressure. A controller controls the set pressure control device to reduce the set pressure more than when the work implement is being operated, when a predetermined determination condition that includes the work implement not being operated is satisfied.
